Abstract

Laser-assisted microvascular anastomoses and nerve anastoriioses can be performed with the most diverse types of laser (1-17). However, postoperative complications in the form of thromboses and aneurysmal sacs as well as neuromas could be detected in longitudinal investigations. By conversion of the beam geometry (1.32-pm Nd: YAG laser, 200-pm, light conductor) and use of two or three concentrically applied 10,0 stay sutures, early and late complications could be markedly reduced. Histological and fine structural analysis revealed a homogenizing change of collagen with interdigitation of altered individual fibrils that appeared to be the structural equivalent of the welding effect (12).
